Mineral glass is the most scratch resistant lens material available, but it is not scratch proof. All OTIS lenses exceed the strictest Australian, USA, and European standards for quality and strength.
However, mineral glass lenses can scratch or crack if not cared for properly. Scratched and broken lenses are not covered under warranty. 
But we all know accidents happen, so OTIS offers a simple and easy way to have your sunglasses repaired or replaced. 
Please print off the returns form, fill in the details, and include it with your carefully packaged sunglasses.
OTIS is not responsible for packages lost or damaged in transit, or costs associated with tracking your parcel. When sending your sunglasses back to OTIS for repair, OTIS recommends tracking your parcel to ensure it ends up in the right hands. In most circumstances we will replace your sunnies with a completely new pair in the same style and lens category. 
Proof of purchase is not necessary for repairs. 
Discontinued styles are eligible for repair subject to the age of the sunglasses and availability. 
We do occasionally sell discontinued styles on our Sale page for less than the cost of our repair service. Simply click on Shop, Sale , to see if your favourite sunnies are still available.
